I have a RX 300 with 57000 miles

I serviced it regularly at a Lexus dealer.

The SUV runs perfectly...


Should I replace the timing belt at that mileage ?

Have something to contribute?

Your probably fine, but some have said time wise the belt should be changed. I would wait till next year, the second stimulus package might provide you one, just kidding. maybe someone can give us the required time/versus mileage thoughts. I know on this engine they will make it an easy 100k miles normally.

I'm at 185,000 miles with my 2000 RX 300 on the original timing belt. However, I have a slow oil seal leak and I was told to wait to change the belt until around 200,000 miles and do all the seals and the belt at the same time. Like you, I have serviced it religiously every 5000 miles at the Dealer until the last 20,000 miles when I switched to every 5000 miles at a local garage who only works on Japanese cars (for half the price). She still runs like a charm

What do you think about that Lenore? I wouldn't recommend to anyone to do that, but I never had any doubt that it would do it. :D

Yea, They are tough belts. But since you and I are knowledgeable, my luck it would have failed....I think He should go buy a lotto ticket...

You're probably right Lenore, but they are still one of the finest made timing belts I have EVER seen. :)

code58,
you are absolutely correct about those belts, they seem to last forever.
I remember replacing T-belts on the four cylinder Porsches at 28,000 to 30,000 miles. Any further and you were asking for bent valves for sure. Or the Fiat 124, any further then 35,000-40,000 miles and you were looking at a new engine.

I am at 63,000 miles on the 2001 RX 300, I guess I've got a bit to go.

Karl- At the risk of insulting you (that's not my intention), you didn't perchance own a 124 did you? I beg to ask the question, why would anyone own one of those? I guess it beats walking (that is if it doesn't leave you walking any way) :lol:
By the way, Karl, at 63k, you're just getting warmed up!

code58,
of course I didn't own one of those 124s, I'd rather walk.
I was in the repair business. Independent foreign auto repair shop for 34 years.
Now I just enjoy my motorcycles.

Karl- NOW I know why you know about the 124. IF you were foolish enough to work on those things, they would keep you in business for sure. That is if you could ever get parts for 'em!

I replaced the belt on my '99 for the first time at 180k, and it still looked clean and solid. The valves arent an interference fit with the pistons, so even if the belt does break it wont do any damage to the motor...you'd just have to get a tow truck.

Oh man here we go again. Interference is what the 1mze engine with VVti valve train is.....Has to do with the variable valve timing....

Ive seen several 1mz-fe (with vvt-i) timing belts break and never wipe out the valves. Do you have proof of prior statement?
